Review on E-Z Lok EK51210 Metric Helical Threaded Insert Kit, High-Quality 304 Stainless Steel, M16-1.5 Thread Size, 16 mm Installed Length (Pack of 5) by Alex May

I ordered the economy kit M14-1.5 (Length 1.5D/21mm) but like the other reviewer I received a kit that was a kit in a different size included. Mine was marked as ordered but included parts for a 1/2-20 (1D/14mm) kit which I identified both by the tap print and compared to the screw to be installed and the picture of the thread pitch of Bolt Depot fasteners. PDF tools (be sure to print at 100% scaling). Please note that you have to stretch the spools to measure according to the pitch pattern: they are not delivered stretched to the nominal pitch length. In the attached picture, the left set is received first, the right set is the replacement. Significantly different content. As I needed this item for a repair this week and Revain didn't have it in stock I contacted EZ Lok directly to see if they could help. They responded within hours and sent me a replacement kit with the correct parts the same day via Next Day Air. They even included a certificate of conformity (certifying that the item delivered matched the item ordered). I'm glad EZ Lok is backing their product and my oil pan is now back in business with a thread rebuild after the drain plug hole. was removed during previous ownership: when I bought this used car there was an aftermarket Dorman shift pin plug and it started to leak). This is my second bolt hole repair using EZ Coil. This is a well thought out product and with that kind of customer service I will remain a customer for life.
